BLlND SLA T ADJUST-ER.

SPEGIFJFCATION forming part of Letters Patent No. 260,622, dated July 4, 1882. Application filed November 14, 1878. I

To alt whom it may concern Be it known that l, GEORGE WILLIAM SPRINGSTED, ot the city, county, and State of New York, have invented a new and Improved Blind-Slat Adjuster, for the purpose of holding blind-slatsin anydesired position, of which the following is a specification.

The invention relates to an improved adjustable device for holding slats of blinds in any position.

The invention consists of a looped lever which passes through an oblong recess in a socket upon the slat-rod, having its lower ends' bent at right angles, one of which carries a ratchetwheeha spring bearing against the teeth of the ratchet-wheel, and a-case mortised in the blind-frame. I herebydeclare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawin gs,"n1aking a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a front view of a blind with the slats closed and the blind slat adjuster attached. Fig. 2 of the drawings represents a vertical section of the same. Fig. 3 of the'drawings represents a cross-section of the same.

Letter A'of the drawings represents a case mortised in the frame of the blind, with a slot or opening in its face.

Letter B of the drawings represents a looped lever, the lower ends turned outward at right angles, one of which carries ratchet-wheel l) and passes through the sides of case A, the upper portion of the same passing through the recessfin socket C.

Letter 0 of the drawings represents a socket with the slat-rod inserted, the lower portion having an oblong recess, through which the looped end of lever B passes.

LetterD of the drawingsrepresen ts a ratchetwheel attached to one arm of lever B and placed in the side of case A.

Letter E of the drawings represents a spring fastened to case A and bearing against the teeth of ratchet-wheel D.

Letter F of the drawings represents a cap fitting over the ratchet-wheel I) and spring E.

The operation of the'blind-slat adjuster is as follows: As the slat-rod is moved up or down it moves the lever Bin a circular direction, and the ratchet-wheel D is made to revolve thereby. The spring E, pressing against the teeth of ratchet-wheel D, holds the slats in any desired position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The looped lever B, adapted 'to engage with an oblongrecess in socket 0 upon the slat-rod, and having its lower ends bent at right angles, one' of which carries ratchet-wheel D, in combination with spring E, caseA mortised in the frame, and cap F, substantially as described.

In testimony'that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE V. SPRINGSTED.
